Hello, If i drive my audi A4 quattro 1.8 T that overheats to 110-115 celsius. Is that hot enough to warp the heads? thanks

141 o2 sensor heater, bank 1, sensor 2

Any codes? could be the crankshaft sensor.battery and connection.

goodyear are tyre mechanics
water in the oil is from a hole in the housing (aluminium timing chain cover ) behind the water pump impeller or problem head
before anything was replaced , a compression test should have been done to determine the condition of the head and head gasket
next a coolant pressure test should have been done to determine if there was a leak in the cooling system ( the housing crack would have been obvious at the test
water pumps always work if there is water for them to work in and only need replacing if there is a water leak from a hole in the housing ( seal failure ) or there is a failed bearing noise
I could suggest that you find an accredited professional service center that has experience on your make of car and get a proper diagnosis before you waste any more time and money on tire mechanics

Please do rate my response. Thanks!

check the belt tension..it might be weak and it making noise when start

Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..

More than likely the fuel pump. This may sound stupid but take something and give your gas tank a bit of a thump. What year is the car?

Could be thermostat this regulates the water flow around the engine to keep it cool sounds like it is sticking open when water gets hot!!

Here is a manual, but you have to purchase it:

There is a small carpeted circle that pops out, unscrew 1 phillips head screw and the tail-light releases
